SPECIFICATION forming part of Letters Yatent No. 734,305, dated July 21, 1903,

Application filed January 19,

To all whom it may concern:

Be'it known that I, FRANCISQUE Cnor'rn, a citizen of the French Republic, residingin New York,borough of Manhattamin the State of New York,l1ave invented certain new and useful Improvements in Processes of Preserving Beer, of which the following is a specifi-.

- cation.

This invention relates to, the preservation of beer or otherliquids; andthe-object of the invention-is to provide a process by which the organic or germ life in the ,beer is rendered harmless, so that the beer will keep without deterioration for a great length of time.

The invention consists of the process of preserving beer which comprises the steps of placing .a suitablepreservative substance in a receptacle in contact with the beerto be.

treated and then passing through said sub stance, receptacle,and" the beer an electric current of high tension, said'current being of such direction, strength, tension,and character as to induce a cataphoric transference- .of said preservative substance through the receptacle into the beer.

The invention consists also in certain other combinations of steps hereinafter described and claimed, all, however, involving the same principle of cataphoric action.

In theac'companying drawings, which illustrate an apparatus in which the process may be carried out, Figure l isaperspec'tive view of the apparatus with.

' parts broken 'away. .Fig. 2 is a sectional elevation of I one ,of. the electrodes, and Fig. "3 shows, the other jelectrode'and its support.

' Similar letters. of reference'indicate corre-l spending parts.-

A indicates cask extends an electrode 0, which-is preferably-in the form-of aitube' provided" at its closed l-o werend with a knob C, the top of the tube;beingbpreferablyen1arg.ed',"as at (3. lfh esteemed with anian'tiseptic, such as} {02 the U. S. Pr stantlardgsolution the inlet of the tube.

the s n'ge,

fsparkgl a powerful spark-coil of "any. suitable size adaptedtdproduce the current ative substance, either solid or 'in solution. lhe tube-is preferably of copper, silvered er:-

'ternally, but may be made of any other suitable substance. The nipple 0 .receives the binding-post D, which thus serves to close At the lower part of the cask at a point preferably directly opposite the electrode 0 is located the opposite electrode'E, also preferably of copper and terminating at its uper. end/in a knob E which is arran 'ed close to or in contact with the cask B. A frame F,

of suitable non-conducting material, secured to the cask by means ofpoin ts F,may be employed for retaining the electrode E in place. The binding-post D of the electrode Eis connected by a wire or other conductor W to one terminal of the secondary spool of the coil, while a conductor W connects the binding-post D with the other terminal of said spool. Within the frame F and in contact with the electrode E, as well as with the cask, is asponge G or wad of any suitable absorbent material, which may be soaked with water or with the same solution as that contained within the tube 0. It is not necessary, however,tha't the sponge G be employed. The same results are obtained when the. sponge is omitted. It is preferable to use however, as the discharge of rom the knob G is thereby spread to someextent. 4 v The process is carried out in this appara* tus as follows: The ask is filled with fullyfermented beer. .The tube-shaped receptacle 0 is inserted in position, as shown an d filled with the preservative substancet- The electrode' E is thenput in place, with the sponge, if used, and the electrical connections made,

so that the tube G fiorms' the positive electrode. In order to produce the transference oi the substance, it'is necessary that the cur:-

rent employed shall be a practically uninterrupted one. When the circuit is in such condition as to yield the wcll-known silent or brushdischargaezitaphoric action will result. The, current is then passed through tnebeer fo'raperiodidf from fiveto-ten'minutes. In order to further insurethe destruction of or- Yganic lifeginjthe beer, itis preferable to sup plefnent, the pamage of the high-tension our rent by passing a current of low tension say one hundred and ten to one hundred and fifty volts-through the beer for five to ten minutes. v

The high and low tension currents .may be obtained from any suitable sources.

The eifect of the passage of the high-tensioncurrent is to convey the preservative substance in the receptacleG in infinitesimal 1o quantities through the tube-wall into ,the beer by cataphoric action. Bythe combined action of the current and, the preservative substance conveyed byit and under its influence the organic life in the beer is rendered '15 entirely harmless, so that the beer will re-,

main in good condition without deterioration in any way for a great length of time. The infinitesimally small quantities of antiseptic are conveyed into the beer under conditions '20 favorable to most eflective action and remaining'in the beer serve toretard thegrowth of new organic life, while the quantity of the substance introduced is so small as not to change the taste of the beer foreign flavor thereto. The process has the further advantage that it can be carried out in a very short time. Having thus described my invention,Iclaim 1 as new and desire to secure by Letters Pat- 3o ent- 1. The herein-described process ot'preserving beer, which consists in pla-cingasuitable preservative substance in a receptacle in contact with the beer to be treated, and then passing through said substance, receptacle and the beer anelectric current of high tension, said current being of such direction stnength,

tension and character as to induce a cataphoric transference of said preservative subor impart any stance through the receptacle into the beer, 4o

substantially asset forth. 2. The herein-described process of preserving beer, which consists in placinga suitable preservative substance in a receptacle'in contact with the. beer to be treated, then passing through said substance, receptacle and the beer an electric current of high tension, said current being of such direction strength, tension and character $0 induce a cataphoric transference of said preservative substance through the receptacle into the beer, and then passing through the beer an electric current of a comparatively low tension, substantially as set forth.

3. The herein-described process of preserv- 5 5 ing beer, which consists in placing-the beer to be treated in a non-metallic, porous vess'el, placing the preservative substance in a receptacle in contact with the beer,"said receptacle forming'the positive electrode of an 6: electric circuit, placing the opposite "electrode at a point outside of said vessel con-1 I taining the beer,- placinga moistened sponge in contact with the-latter electro 'e' 'fand. the vessel, and passing an electric curreht of high tension between said electrodes, said current being of such strength, tension and character as 'to induce a cataphoric' transference of the preservative substance through the receptacle into the beer, substantially as. set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses A FRANCISQUE CROTTE.
